HAYWARD -- A 31-year-old woman thrown more than 100 feet in a hit-and-run crash in Hayward this week remained in critical condition on Friday, police said.

Officers were called at 6:13 p.m. Wednesday to the southbound lanes of Hesperian Boulevard near Tahoe Avenue for a report of a pedestrian hit by a vehicle, said Sgt. Chad Olthoff.

When police arrived, they found the woman unconscious in the roadway.

The woman, police said, was walking west on Hesperian in a crosswalk when she was hit by a car traveling south on Hesperian Boulevard.

The impact, Olthoff said, threw the woman 112 feet.

She was taken to a hospital where she underwent surgery for life-threatening injuries, police said. As of Friday, she remained in critical condition, Olthoff said.

After the crash, Ormsby said, the car did not stop. The car was described as a black, newer model sporty-looking sedan.

About 10:45 p.m. Union City Police Department officers located a car matching that description on Chippendale Lane and police learned that neighbors watched someone park the car about 6:20 p.m. After the car was parked, witnesses told police that two males got out of the car and ran away.

As of Friday no arrests had been made.

The crash remains under investigation. Anyone with information about the incident is asked to call police at 510-293-7034.
